Figure 3 Function classification and subcellular localization analysis for differentially expressed proteins in P. massoniana seedlings growing at various calcium levels. (A) Function classification. (B) Subcellular localization predication.
These DEPs showed a wide subcellular localization and cellular component distribution (Figure 3B), among which chloroplast (48.6%) and cytoplasm (29.7%) were the dominant subcellular distribution compartments. Mitochondria localized proteins and nucleus localized proteins accounted for 4.0% and 4.0%, respectively. A small proportion of proteins were predicted to localize to extracellular (1.4%), membrane (1.4%), peroxisome (1.4%) or Golgi apparatus (1.4%). Besides, 8.1% proteins had no definite subcellular localization distribution.
